Application filed October 27, 1922. Serial No. 597,379.

To all whom it may concern:

Be it known that I, OTIS W. ORMSBY, a citizen of the UnitedStates,residing at Hill City, in the county of Pennington and State of SouthDakota, have invented a new and useful Wrench, of which the following isa specification.

The object of my invention is to provide an improved wrench fortightening the bolts that secure fish plates to rails, andparticularlyto provide a device of this kind having novel means foradjustment of the operating lever. I attain these and other objects bythe mechanism shown in the accompanying drawings, in which-- Figure 1 isa side elevation of my invention in use;

Fig. 2 is a section on line 22 of Fig. 1.; and

Fig. 3 is a side elevation of the invention from the reverse side ofthat shown in Fig. 1.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings, I provide opposite plates 1 and4, rigidly connected by the metal straps 3 which extend across the rail.Mounted in spaced relation to plate 4 is a slotted arcuate plate 5mounted on bolts or rivets 6. Plate 4 is provided. with an arcuate slot8 with which the arcuate slot 7 of plate 5 is aligned. I provide anoperating wrench member or handle 9 having a longitudinal slot 10,through which extends the bolt 11 which is mounted in slots 7 and 8 inwhich it is slidable throughout the entire arc of the slots. Wrenchmember 9 is provided with a wrench head 12 adapted to engage the nut 13of bolt A...

As shown in Figs. 2 and 3, I provide a suitable slot 13 in plate 1 toreceive the head of the bolt which is to be tightened. To prevent thebolt from working out of place I provide a strap 2 attached to theexterior portion or" plate 1 and extending across the opening 13 toengage the outer surface of the head of the bolt A, as shown in Fig. 2.

The operation of the device will be understood from the foregoingdescription in connection with the accompanying drawings. The device ispositioned over the top of the rail with the slot 13 receiving the bolthead. The wrench handle 9 is operated manually, being slidlongitudinally on member 11 until the head 12engages a nut. The

wrench handle is then manually operated .90 degrees, a third plateriveted to said slotted plate said third plate having a similarlyaligned slot, a wrench handle, and a bolt extending through the wrenchhandle and through the slots in the aforesaid slotted plates, the boltbeing slidable in the slots to permit of manual operation of the wrench.

2. A wrench of the class described, comprising spaced p1ates,one of theplates being slotted to receive the head of a bolt, straps rigidlyconnecting said plates, one of the plates extending substantially abovethe rail on which the wrench is used and having an arcuate slot, saidslot extending through an arc of approximately 90 degrees, a spacedslotted guide plate having a like arcuate slot aligned with the firstmentioned arcu ate slot, a wrench handle, a bolt extending through thearcuate slots and through the wrench handle to operatively connect thewrench handle with the plates, the bolt being slidable in the arcuateslots, and a slot in the wrench handle extending longitudinally oithehandle and through which the aforesaid bolt extends to permit ofadjustment of the wrench handle to engage the nut to be tightened atvarying positions relative to the top of the rail on which the wrench ismounted.

3. In a device of the class described, the combination of rail-engagingmeans, said means being slotted to engage the head of a bolt, spacedplates mounted on said means, said plates having arcuate slots extendingthrough an erect approximately degrees, a wrench having a longitudinalslot in the handle thereof, a bolt slidably mounted in said slottedportion of the wrench handle and also slidably mounted in the arcuateslots of the spaced plates, whereby to pen mit a wide range of operativemovement of the wrench. Y

4:. In a device ot the class described, the

combination of rail engaging means includcuate slots when the Wrench isin use, a bolt ing means for engaging the head of a bolt, slidablymounted in all the aforesaid slots spaced plates afiixed to saidrail-engaging and extending throughthe slotted portion 10 means, saidplates having arcuate slots thereof the Wrench handle, for operation asherein, a Wrench having a slot extending longitofore described andshown.

tudinally of the handle thereof and extenda ing to a position oppositethe aforesaid ar- OTIS W. ORMSBY.
